While any girl or boy can, technically, grow up to be president, only Tina Fey can become Sarah Palin, at least on "Saturday Night Live."
And even for her, that means a hairdresser, a team of wig makers, colorists and a pound of human hair.
"A wig takes 40 to 50 hours to make," said Bettie Rogers, the show's head of the hairstyling department. "We read the sketches on Wednesday night to determine the wigs to be built at Bob Kelly's, a wig maker on 46th Street. The ladies who make the wigs work around the clock until Friday night, sometimes even late Saturday."
